HERMAN KRUTZSOH, OF ST. LOUIS, MISSOURI.

BRlCK- MACHlNE.

SPECIFICATION forming part of Letters Patent No. 393,246, dated November 20, 1888,

Application filed April 11, 1888.

To all whom it may concern:

Be it known that I, HERMAN Kau'rzscn, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Brick-Machines, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of this specification.

This invention is an improvement on the brick machine patented to me under No. 345,513, bearing date July 13, 1886, to which reference is made for a general description of the machine.

The present improvement applies more especially to the described means for arresting the approach to each other of the mold-plungers while the charger is passing between them, and to the described means for arresting the descent of the lower plungers.

Figure I is a side elevation of the machine with the clutch-pulley and clutch removed. Fig. II is a horizontal section at II II, Fig. I, the parts, however, being shown at the oppo- Fig. III is a vertical longitudinal section at III III, Fi II. Fig. IV is a front elevation, part in section. Fig. V is a detail transverse section atV V, Fig. II.

The main frame is marked 1.

2 is the main shaft, turning in bearings 3.

4 is a loose pulley on the shaft, receiving the drive-belt. The hub 5 of the pulley has end bearing against a collar, 6, that is fixed to the shaft.

7 is a clutch-wheel, which has endwise mo tion on the shaft, but has spline or equivalent connection with the shaft, -so that it turns therewith. The periphery of the clutch-wheel hasa flange, 8, which engages in an annular groove, 9, of a circular ring, 10, which is secured to the side of the pulley 4, or is cast in one piece therewith. \Vhen the clutch-wheel is moved toward the pulley 4 and the flange 8 forced into the groove in the ring 10, the pulley 4 is turned around with the shaft 2.

The clutch-wheel 7 is moved to and from the pulley 4. by a hand-lever, 11, whose forked end 12 has slots receiving studs 13 upon a yoke, 14, which isin a circumferential groove of the hub of the clutch-wheel. The clutch-lever works on a fulcrum at 15, and has a handle, 16, in easy reach of the operator standing The main shaft carries two Serial No. 270,283. (No model.)

spur-pinions, 17, that engage the two cam wheels, 18, upon separate shafts. These carnwheels have upon the outer sides cams 19, by which the charger is movedforward and backward to fill the molds 21 and carry back the superfluous earth. No novelty is herein claimed in connection with the charger or manner of actuating it.

The upper plungers, 22, and lower plungers, 23, are forced toward each other by levers 24, operated by toggle-links 25, as in my aforesaid patent, to which reference is made for a description of the molds, their connection with the actuating-levers, and method of operation in general. This present improvement, how ever, contains a novel device for arresting the descent of thelower plunger, 23, which novel device will now be described. (See Figs. I, II, and IV.)

26 are blocks working vertically in guideboxes 27, and having at their upper ends cups 28, which receive blocks 29, of rubber, upon which the bottom of the plunger 23 impinges as it descends. Each of the blocks 26 has a screw-threaded socket, in which is a screw, 30. The screw 30 has a fixed collar, 3l,which rests on a rubber block, 32,that is supported on the fixed support 33. The extension 34 of the screw 30, below the collar 31, passes through the spring-block 32 and the support 33 and through a central socket of a miter-wheel, 35, with which it hassplineconnection, so that as the miter-wheel is'turned the screw 30 turns with it, while at the same time the screw has vertical movement independently of the miter-wheel. Thus as the miter-wheel and the screw are turned the block 26, with its abutting block 29, is raised or lowered and the descent of the lower plunger regulated as may be desired. Forthe convenient turning ofthe two miter-wheels 35,and to insure their equal rotation, they engage with miter-wheels 36 upon a single shaft, 37, which carries aniiterwheel, 38, engaging a miter-wheel, 39, on a hand-shaft, 40, that is turned bya hand-wheel, 41.

In the absence of the lowerspring-bloek, 32, the block 26 would rest upon the unyielding support 33 and the screw-threads of the block 26 and screw 30 would be subjected to an amount of strain much greater than is the case when the spring-block 82 is placed be tween the block 26 and support 33, as herein described, for the spring-block 32 allows the block 26 to move downward on the impingement of the plunger with the block 29, and thus very much lessens the strain.

The toggle-links 25 are strap-jointed to the ends of the levers 24, and their other ends strap-jointed to bearings 42 of the cross-head 43. The cross-head carries anti-friction wheels 44 and sliding blocks 45. The wheels 44 travel between guides 46 of the main frame, while the blocks 45 slide along rails 47 of the main frame. At 48 are seen lips which engage beneath the rail 47 and prevent the blocks 45 throwing up.

49 is a rod strap-jointed to the cross-head 43 at one end, and having at the other end a vertical cross-head, 50. This cross-head is be tween the two cam-wheels1S,and has upon its sides separate cam-grooves, 51, that receive anti-friction rollers 52 upon wrist-pins 53, fixed in the cam-wheels. As the cam-wheels rotate it will be seen that the cross-heads 50 and 43 will be moved longitudinally and the plungers 22 and 23 operated by the levers 24. \Vhile the upper plungers are in their elevated position and the lower plungers are in their upper position the charger moves forward,and while the upper plunger is still elevated the lower plunger falls and the charger moves backward. To give time for the charger to get out of the way of the upper plunger while the charger is moving backward, the movement of the plungers is arrested for a short time by making the part 54 of the camgrooves 51 concentric with the cam-wheels 18 when the cross-head is in its forward position, as seen in Fig. III, so that while the rolls 52 are traveling along that part of the grooves the cross-heads, and consequently the plungers, will remain at rest.

The cam-grooves 51 are coincident or diametrically opposite each other in the crosshead; but they are divided by the Web 51. My purpose in doing this is to provide against lateral movement of the cross-head upon the rollers or studs which work in the cam-grooves, for it is readily seen that without the web 51 the cross-head would be at liberty to vibrate hack and forth on the studs and against the cam-wheels, and thus produce a great deal of wear and destroy the perfect movement of the parts.

To prevent the vertical movement of the cross-head 50 it has a pin or stud, 55, carrying an anti-friction roller, 56, which works between horizontal guides 57. (See Figs. II and III.)

For explanation of the details of the machine not herein described, reference is made to my patent, No. 345,513, before cited.

I claim- 1. In a brick-machine, the eombination,with the mold-plungers, the cam-wheels 18, and the cross-head 43, for imparting motion to the mold-plungers, of studs on said cam-wheels projecting in opposite directions, and the cross head 50, connected to cross-head 43 and having cam-grooves, in which said studs engage, substantially as set forth.
